First of all thanks :)
You can somethimes get get stuck platforms edge, thats true, i didn't have enough time to solve it and i didn't consider it as a major problem..
I don't know what did you trigger something above the platform, i really did not notice that (Did you hit spikes which was on a platform above you? I can't imagine that in another way... But i didn't have a issue like that while playing?)
I am quite sure dash works everytime, can you explain it better because i am quite sure it was working properly.. (If you meant only left-dash works, that is not actually the case, You can press right mouse button for right, left mouse button for left dash, if your problem was something different please tell me :) )
I am glad you liked it! I feel happy when i am able to entertain someone with my game :)
